    You can check the quality of reinforcement at the site in three ways.

    1. Mass per run meter – take 4 number of cutting bar of length 1 meter and check the average length and weight of each and check the mass per run meter.

    2. Bend test – bend test should be followed IS code 1599, and the rebar sample should be bend 180° as per IS 1599.

    3. Rebend test – first bend the rebar sample at 135°, and after that, keep it in boiling water of 100° C for 30 mins. After cool it down, bend it into 157.5°, and rebar should not show the crack or any rupture during this bend.

    1. Check for brand and grade of the steel which is mentioned on the bar.
    2. Check for diameter of the steel.
    3. Check for corrosion of the bar, it should not have any rust.
    4. Also we can check the Manufacturers Test certificate which will come along with the steel.

    These are all visual checks we can do immediately at site level.
